round up Stock protection Biomass control
O ver the last three years Hvalpsund has been involved in
developing a revolutionary new stock protection system for Huon
Aquaculture in Tasmania,Australia. Huon is a vertically integrated
company, farming, processing and selling premium quality Atlantic
salmon and rainbow trout products to domestic and international
markets. As the only 100 percent Australian-owned salmon farming
business in Australia, Huon employs over 480 staff and will produce
around 15,000T of salmon and trout this year Huon owners, Peter and
Frances Bender approached the Danish net manufacturer at Aquanor
back in 2011, as they wanted to find partners to develop a new
system to keep out seals and birds. Seals, in particular, prove a
real headache in Tasmania, costing the company in the region of
Aus$12-18 million per year. These costs come from direct losses
caused by seals getting into the pen and killing the fish, as well
as the impact of stress induced in the salmon by the seal attacks.
Moreover, the risk of attacks means that the company needs to have
dedicated teams of staff patrolling the marine farm leases day and
night in an attempt to keep seals away from the pens and off the
collars, as well as employing extra personnel to release any seals
that get into the pens. Not only is killing seals strictly
forbidden in Australia, but any death of a seal would also be very
negatively perceived by the public. As a result, the company
recognised that huge savings could be achieved by develop- ing a
better way to fence off the seals from attacking fish and to
improve safety for per- sonnel working on the farms. They had tried
various net materials in the past, but with poor effect and now
they wanted to go into a completely new direction that would
improve safety for both fish and personnel. Hvalpsund suggested a
trial using the ultra- strong and light Dyneema fibre for the nets
a material they have plenty of experience of working with. Some of
the early tests showed that it was not enough just to spec up the
twine size, however finding the right combination of twine size and
strength and combining both knotted and raschel knotless materials
eventu- ally proved to be the key. As no other salmon farm in the
world had ever required nets with such high strength, the project
was truly revolutionary. By trialing different kinds of nets and
pens Hvalpsund worked with Huon to determine the best system to
keep seals and birds away from the fish and feed. Key to the design
The key to the design is the use of an extra-wide, triple-collar
stanchion that has specialised outer sockets to accommodate a seal
fence post and bird net pole. The seal fence post allows an outer
seal fence net surrounding the entire pen to rise 2.8 metres above
the surface of the water. The idea of the extra wide pen is to
main- tain a good degree of separation between the outer seal fence
and the inner containment net. The outer seal fence net is made
using 125mm black knotted Dyneema with a breaking strength of over
1200kg. It is also fitted with strong Dyneema vertical ropes from
which the sinker ring is suspended by hanging the heavy sinker
rings directly from the seal net it is kept as tight as possible
all the time, which makes it more difficult for the seals to push
the net or bite it. The inner containment net is made with light
yet strong Dyneema which ensures good water flow through the pen
and reduces fouling. As the outer seal net is permanently in place,
the pen is kept as a safe work environ- ment where daily operations
or net changes can be done without the risk of seals attacking
stock or personnel. The wide clearance between the outer seal net
and inner containment net means that the nets can be cleaned using
in situ net wash- ers. The system also includes an ultra-light bird
net that is suspended high above the surface by light, flexible
poles. The specially-designed, injection-moulded HDPE stanchions
can be fitted with walkway plates either between the inner collars
or both collars. This design provides a safe work- ing space for
doing daily operations on the pens, even in bad weather. The
advantage of using a pen made with only HDPE is that it requires
far less maintenance than pens with steel components. Huon is also
now investi- gating the potential for the pen stanchions to be
constructed with injection-moulded nylon which, if successful, will
make the stanchion even stronger. The original trial has proved to
be so suc- cessful that Huon has now decided to replace all their
existing pens with the new system. However, the real benefit will
not come into play until all the pens at the site are replaced as
long as some of the pens with the old design are still in use the
seals will target these. Hvalpsund Net is a family-owned and -run
company based in Denmark with 20 employees in the headquarter,
warehouse in Hvalpusnd. The company has its own pro- duction in
Poland with 80 workers mainly assembling aquaculture nets. Main
export areas are Faroe Islands, Iceland, Scotland, Spain, Malta,
Malaysia and Tasmania. The focus at Hvalpsund Net is to make cages,
nets and mooring system for offshore aquaculture sites. Stock

FISH FARMING TECHNOLOGY
IT GOES WITHOUT SAYING THAT YOUR BUSINESS STANDS WITH THE RIGHT
INFORMATION BUT CAN FALL BADLY WITH INACCURATE WEIGHTS AND FISH
NUMBERS. T hats a quotation by Steve Bracken of Marine Harvest
Scotland which Hermann Kristjansson, CEO and co- founder of Vaki
Aquaculture Systems Ltd, began his talk at Aquaculture UK 2014
recently in Aviemore, Scotland. Mr Kristjansson presented his
experience and views on Biomass Control, which has been listed as
one of the challenges in Scottish salmon farming and in salmon
farming in general. Started Vaki when he graduated from the
University of Iceland in 1986. Since then he has concentrated on
developing fish counters and size estimators for fish farming.
Three years ago, Marine Harvest, Salmar and Leroy formed a pro-
ject with SINTEF in Norway, the largest independent research
institute in Scandinavia, to improve the Biomass Control in salmon
farming. The total budget of the project, called EXACTUS, was UK3
mil- lion, which confirms the importance of Biomass Control as seen
by these three companies. A recent study conducted by PHD student
Arnfinn Aunsmo from Aas University in Norway shows that the error
in number of fish and average weight harvested from individual
cages is high. The error reported on average weights is more that
+/- five percent in 30 percent of the cases. There is evidence that
show similar figures in Scotland even though aggregate results
often show that people are harvesting approximately what they
expect from a complete site. Serious problem Biomass Control is
considered a serious problem/challenge in fish farming. Now, why is
it a challenge? Everybody can agree that poor bio- mass control can
lead to unnecessary negative environmental impact. But what Mr
Kristjansson addressed is the challenge of getting the most out of
production: How to achieve maximum yield with minimum cost. Very
few people are concerned with the profitability of salmon farming
today given the current price of salmon. But over the past 28 years
that Mr Kristjansson has been in the industry, prices have not been
very stable and he thinks it would be considered irresponsible not
to prepare for some price fluctuation in the near to medium future.
In order to achieve maximum yield at minimum cost, higher indus-
trialisation of the farming process is required. Tight monitoring
and control of factors, that can be controlled, is needed. We need
to collect as much data as possible and go into as much detail as
possible monitoring exact weights and numbers all the way from
hatching to harvest, he explained. Mr Kristjanssons experience is
that numbers in freshwater are quite reliable in Scotland. All
freshwater producers are using Vakis Micro and Macro Fish Counters
successfully. Vaki would like to conduct regular training to make
sure there are no surprises and everybody is up-to- date in the use
of the equipment. Smolt delivery One of the most critical points in
production from a Biomass Control perspective is the smolt
delivery. The number and weight of smolts introduced into each cage
is absolutely critical because it represents the starting point in
an ongoing production. Things could also be improved here with
regular training and regular validation of counts from the
wellboats. As many of you know, our counters record the counting
process so counting can be validated afterwards and in fact, if the
customer doesnt want to do it himself, they need only to forward a
recording file from the counter to Vaki. Currently, we are
developing an online database which will receive and store these
recording files automatically from customers for later reference or
validation. Accuracy needed The ongoing part of the production is
the most challenging for biomass control. Taking a manual sample of
100 fish from a cage is both physically challenging for the fish
and the fish farmer and it is just not accurate nor reliable
enough, referring again to Arnfin Aunsmo in Norway and to
statistical theory. There is a case study from EWOS Innovation in
Norway that shows this clearly, he says. When the information about
the Biomass in individual cages is not available or inaccurate,
growth cannot be monitored and feeding not controlled in an effort
to obtain the lowest feed conversion rate possible. Low FCR is of
course one of the most important indicators of low production cost
as you know, he adds. Therefore, monitoring the FCR based on real
growth is essential if one wants to control the feeding. Monitoring
the periodic FCR based on real growth is also essential if you want
to analyse high FCR periods and takes some actions or implement
improvements before the next production period. He says a company
might want to reduce its FCR from 1.4 down to 1.2. How can they do
that without knowing the real growth over short periods? he asks.
Biomass Control helps industralise salmon farming further 04 |
INTERNATIONAL AQUAFEED | Fish farming Technology FISH FARMING
TECHNOLOGY
Monthly hand sampling of 100 fish does not provide enough
accuracy to build results on. Vaki have been working with its
customers to identify and focus on periods of high FCR in order to
identify the reasons behind this and improve the situation. The
only way to monitor and improve FCR is to measure real growth
continuously and accurately. He quoted another example, saying a
customer in Canada, who monitored the growth with Biomass Daily,
confirmed a very high FCR for two months. When analysing the period
the customer found out that due to very high currents, some of the
feed drifted through the cage before the fish could eat it. The
customer is going to try to avoid this next production cycle by
moving the feed input towards the current and perhaps try to feed
the fish when there are low tidal currents. Future developments The
Biomass Daily system has been developed for some years now and Vaki
will continue to develop it to provide even more valuable
information to the customer. Vaki will do this by comparing cages
in the same site with cages in another site, benchmarking with
anonymous cages in the area and comparing with the last production
cycle. Vaki have developed a sonar specifically to find at which
depth most of the fish are in the cage, to put the frame there in
order to measure most fish and a winch system to move the frame
between depths. Biomass Daily can be used to monitor the biomass
from hatching to harvest. Vaki have developed a morts counter with
LiftUP from Norway. The morts counter will automatically send data
to the Biomass Daily system to make sure that the number of fish in
the cage is maintained accurately. According to major sources,
Biomass Control is one of the biggest challenges in salmon farming.
Biomass Control is also one of the big- gest opportunities in
salmon farming as a part of increased industriali- sation of the
fish farming process which needs to take place in order to meet
future challenges. Fish farming Technology | INTERNATIONAL AQUAFEED

Email: [email protected] | www.was.org MAG Seal Deterrent At the
time of the Aquaculture UK con- ference and exhibition, the MAG
Seal Deterrent had only been on the market for six weeks - a new
exciting piece of kit set to save fish farms a fortune. Of course
we at IAF were keen to learn the facts and Mal Scott, general
manager for Mohn Aqua UK, based in Forres, Scotland, was more than
happy to talk us through the product. The Airmar DB11 used to be
imported and sold here in the UK by Mohn Aqua. The DB11 was for a
long time, the best Seal Deterrent on the mar- ket but now, with
Airmars blessing Mohn Aqua have taken the DB11 and redesigned it
for the better, creating what is now known as the MAG Seal
Deterrent. It is made fully in the UK and has been built in
consultation with, approved and tested by Airmar. Sturdy
foundations Its foundations are sturdy, using much of the
technology that the DB11 originally incorporated. Just like the
DB11 the MAG Seal Deterrent sends out an omnidirectional pulse that
hurts seals ear drums, yet with the MAG deterrent, The pulse on
each projec- tor can be set to go off at different intervals and
for varied lengths of time, making the sequence appear random. In
the past, some seals had learned to predict a pattern. The MAG Seal
Deterrent is 50 percent more effective than the DB11 and so it
further helps prevent losses. Its only been on the market for a few
months. A company reported UK91,000 loss then got a new MAG Seal
Deterrent box fitted and didnt lose a single fish. Companies have
to keep good records of seal attacks and seal deterrents. Mal
explained all supermarkets audit the fish farms where they source
their fish, using standard industry auditors in the UK like the
RSPCA and Freedom Food Alliance. None of the old systems would tell
you if the system was faulty, the only way of knowing was to lose
fish to seals and with the MAG Seal Deterrent its easy to find out.
explained Mal. Fault detection can be done daily with the MAG Seal
Deterrent. A main problem that used to go undetected quite often
was a damaged projector cable. But when you go through the test
sequence each day - these things are easy to identify. The product
works by firing a pulse that can cause pain to a seals eardrums
within 60 metres of a fish farm. Seals can get used to noise but
not pain; yet it wont deafen seals as alternates through many
frequencies. MAG was conscientious when it came to cetaceans
(whales, porpoises and other mammals) and is confident that the MAG
Seal Deterrent causes little acoustic interfer- ence to them.

Feed barge innovations for the Faroe Islands JT Electric and
Sandgrevstur joined forces to create innovative feed barge
solutions for Bakkafrost, the leading producer of top quality
salmon in the Faroe Islands. Oddvald Olsen, Bakkafrosts farming
manager has been work- ing in the sea-farming industry for nearly
30 years. During that time he has been following the development of
feed barges. In his opinion, traditional feed barges are not
suitable for the farming environment in the Faroes. Mr Olsen had
been contemplating the idea of creating a suitable solution for
many years. Now, JT Electrics Olavur Thomsen and Sandgrevsturs
Gordon Martin Midjord have made that idea a reality. Some were of
the opinion, of course that we went back in time by rebuilding
out-of-date cargo vessels into feed barges, explained Olsen. But as
these vessels are built for sailing the open seas and the hold is
quite suitable for silos, I was convinced they were right for the
project. The capacity to carry Sandgrevstur largely sell and
transport raw material for con- crete and asphalt production. They
are always on the look out for ships that have the capacity to
carry a large amount of cargo and they always know which ships are
on the market. This combined with JT Electrics knowledge of feeding
systems makes for a winning union. Back in August 2013 Skavahamer -
the first of the custom- made feed barges was delivered to a
Bakkafrost fish farm. Skaverhamer was a succeeded by a second
vessel Svarthamar, which was delivered to another Bakkafrost
feeding site in April this year. Each fish farmer was involved with
the process of designing the barge to meet the requirements of the
site. The feed barges are unique and built according to customer
demands yet they share defining characteristics. Each barge is
extremely stable and suited for exposed sea. They are high capac-
ity and can carry 600 tonnes of feed or more. Each feed barge has a
very long berth side enabling feed and work-boats to safely lie
alongside and both have a high life expec- tancy due to the
thickness of the steel from which it is made and each vessel has
large fuel and water carriage capacity. The up-cycling aspect of
these feed barges is appealing and is economically rewarding. JT
Electric explained it is not always about using the most expensive
materials, it is more about using the materials that are right for
the job. And in this case they hit the nail on the head. The barges
work just as well as I had imagined explained Mr Oddvald who says,
We are quite satisfied with them as they are suited to their
position in the open sea, where the waves are high from
time-to-time. Dryden Aqua active filtration media Dryden Aquas
exhibition stand at Aquaculture UK 14 was laden with little sample
sachets of emerald green Active Filter Media (AFM) that people were
urged to pick up and pocket. I have pinned the little sachet onto
my notice board at work! For me - it serves the purpose of a
souvenir and brings back memories of Aviemore and Aquaculture UK;
forget stuffing a suitcase full of haggis and bagpipes. Staring at
this little sachet of AFM is enough to take me back to the
highlands. Obviously, it is so much more than a souvenir and the
little sachets also fell into the hands of some of the big names in
aquacul- ture; all of whom could be seek- ing innovative filtration
solutions within the aqua sector for filtration purposes. AFM is
made in the most sophisticated glass plant in Europe from recycled
Scottish green glass cullet and bottles. The Dutch olympic team
train in AFM- filtered pools and thats understandable as this
report shows AFM is confirmed to be twice as good as the best sand
or glass filtration media in cleaning water. Let me just conclude
by saying how charismatic and informative Drydens representatives
were. Analytical chemist Christi Ashley Sing and engineer Mutassim
Ghzali were great ambassadors for the product. www.drydenaqua.com
Stirling graduate appointed by Meriden Animal Health University of
Stirling graduate Kat Konstanti has been appoint to the position of
International Technical Support Specialist for Meriden Animal
Health. Ms Konstantis main focus will be to support the drive and
growth of Meriden's products in the aquaculture industry through
her technical knowledge and understanding of the market. She
recently graduated with a Masters in Sustainable Aquaculture.
During her studies at Stirling in Scotland, Ms Konstanti
investigated several aspects of aquatic animal culture and gained a
solid understanding of the principles that surround the aquaculture
industry. With a focus in aquatic animal health control, nutrition,
food safety and practical feed production, Kat's studies have set
her up well for her career with Meriden. Kat will also be providing
addi- tional technical support to the other species areas of the
business; however her main focus will be on aqua. "Meriden has
gained a solid base in the aquaculture industry since
re-formulating its flagship product to create Orego-Stim Aquatract
and developing Phyconomix," says Kat speaking of her appointment.
"It is my goal to continue the development of these products within
the aquaculture industry which is in dire need of effective,
natural and sustainable products." Orego-Stim Aquatract has been
formulated to reduce mortal- ity, increase harvest weight per area
and provide support against stress during vaccination and grading.
The product is available in both liquid and powder form. Phyconomix
is a ready-to-use range of algae-based products that mirrors
optimal larval diets encountered in the wild. Available in powder
and liquid form, the nutritionally complete products produce
healthier, more resistant post larvae for on-growing.

Remote interface assists controlling feed and fish in transit
Pentairs new Remote Interface Unit (RIU3) is a modular system that
offers a high level of monitoring and control when it comes to feed
in transit and in storage. The original RIU was a great achievement
in linking the vari- ous stages of fish transportation. However,
the new RIU3 which took a year in development and is based on
customer inputs, is set to further its capabilities while providing
a user experience that is less complicated through more simplified
controls of just four buttons. International Aquafeed was
interested to learn at Aquaculture UK 2014 about the installation
of RIU3 on monitoring multiple trailers carrying live fish
simultaneously. This utilises five direct inputs and five relay
inputs to monitor the fish accurately and ultimately lead to
reduced operating costs. Arvotec, the Finnish company who have
previously featured in our magazine, use real-time software from
Pentair in their products. Higher waves, stronger currents do not
upset Faroe fish farmers Battered by extreme weather and sea
conditions in a natural envi- ronment far more hostile than most
other places, Faroese fish farms are built to last, using the most
robust equipment in the world, according to Vnin Aquaculture. For
most fish farmers, a wave height of eight metres is rather
unthinkable, not to mention a current strength of 0.8 metres per
second. Now go to the Faroe Islands and you will soon see that such
conditions are considered nothing out of the ordinary - that is,
they are quite common during winter in certain locations, as
measured in 100-hour blocks. Extreme conditions by Faroese
standards, is quite a different thing. Back in November 2011,
Landsverk, the Faroese Public Works Agency, recorded wave heights
of up to 19.7m, in fact the highest ever since records began in the
late 1960s - possibly the highest on record anywhere, according to
the agency. Even on that occasion, Faroese fish farms largely
suffered no significant damages, however, one installation had its
anchorage compromised and started drifting. I remember this person
was nervous about his fish farm which had shifted position by some
70m in a very short time, said Signar Poulsen, manager at Vnin
Aquaculture. One of his larger floating frames had snapped and was
only being held together by the net cage itself, which fortunately
was made of very strong Dyneema netting. So this was an emergency
situation and we had three service teams mobilised to make sure the
fish farm remained safe. It turned out to be intact except for the
anchors used for keeping it in place and the one floating frame
which had been broken in two but was held together by the net cage
itself. We had it all repaired and back in place in a matter of
hours. The anchors were of the most robust kind but they had been
dragged across the seabed by the force of the sea with the upper
parts completely deformed. So the person was very happy to see
everything resolved and the installation back in place with no dam-
age to the fish farm. Mr Poulsen added, But such incidents are
extremely rare in the Faroe Islands; I cannot recall any other time
that something like this happened. Three times stronger Out of a
total of 36, two fish farming locations in the Faroe Islands
regularly have currents of up to 0.8 metres per second while two
other have wave heights of up to eight metres. As far as con- cerns
equipment, the ability to withstand the elements is a standard
requirement. Today, every aquaculture installation in the Faroes
uses equip- ment from Vnin Aquaculture, Mr Poulsen says. Our
offerings range from complete solutions to component parts, from
net cages, plastic cages, to mooring systems and acces- sories.
Vnin net cages are usually made from nylon, dyneema, polyester or
polyethylene. What separates a Vnin net cages from others is the
design of the net cage. A Vnin net cage is designed in particular
way which enables it to be used at more exposed and shallow sites.
Fish farms are essentially underwater installations and according
to Vnin, their mooring system outperforms other systems on the mar-
ket, much thanks to a unique design that includes a shock absorbing
function that enables the installations to remain firmly moored to
the seabed while seamlessly withstanding the forces of the sea. We
have 14 departments spread over the whole North Atlantic Ocean,
spanning five countries. Canada, Greenland, Norway, Faroe Islands
and Denmark, he says. Vnin net cages and mooring systems undergo
rigorous quality tests in order to ensure strength and quality is
never compromised. All Vnin products come with certifications.
Ropes from Knox Star Netting is a product with a worldwide patent
pending for the fibrous polymers used and consists of new ropes
from W&J Knox a company first established in 1778 and having a
range of purposes to meet many challenges in fish farming. The
unique properties are hydrophobic qualities and easy clean- ing; no
algae or other materials in the water are able to stick to it. The
benefits of the technology have been developed with other partners
to deliver superior technology with friendly, built-in anti-seal
strength ropes for fish farmers. The technology is at a very high
level but is not just for aquacul- ture, says the company.
Kaycees twin-dose syringe Kaycee is offering a new twin-dose
syringe that is the culmination of significant research and
development in response to the needs of the aquaculture industry.
Samuel and Adam Sesemann told International Aquafeed maga- zine
that Kaycee has been building high-quality, hand-held repeater
syringes serving the international animal health industry for over
50 years. For use with all oil and water-based vaccines, it is
known for reliable dose accuracy while still being easy to maintain
with fully replaceable spare parts. With its distinctive blue grip
and polished chrome finish it has changed little over the years and
due to its truly ergonomic and well-balanced design their syringes
are com- fortable to use, allowing long sessions while mini- mising
operator-fatigue and ultimately reducing costs. Built with chrome-
plated metal to ensure a long life and endure the rigours of
outdoor use in the agriculture and aquaculture industries. As with
all our syringes the hand-operated, twin-dose repeater syringe has
been designed for use with all oil and water based vac- cine and
specifically designed to deliver two vaccines of differing
viscosity in the same dose. It has two adjustable dose ranges of
0.05ml each, 0.1ml each or 0.05ml and 0.1ml. Staying true to the
design of our current syringe range it is comfortable to handle,
ergonomic in design, allows for long sessions minimising operator
fatigue and will ultimately reduce the costs of vaccination, says
the company. Kaycee Veterinary Products Ltd was founded in 1962 and
has been owned and run by the Sesemann family since 1976. Based in
England, their products are shipped internationally. Fish farming
